式の選局装置は公知である。[Detailed description of the invention] Conventionally, a plurality of rod-shaped tuning members, each made by having a threaded part in the middle and having square moving pieces (frequency storage members) screwed into the threaded part, are slid on a base frame. When this tuning member is pressed forward against the restoring spring, the moving piece is pressed against the front edge of the slide plate that interlocks with the variable tuning element, and this state is transferred to the lid frame. It is held by the attached holding plate, and then the knob provided on the tuning member is rotated.
A screw-type channel selection device is known in which a slide plate is moved and displaced together with a moving piece, thereby causing the moving piece to memorize the tuning point of a station.
